摘　　要：根据模糊综合评价原理、MapGis和Sufer绘图软件技术对清原县浅层地下饮用水进行综合评价。首先,通过野外采样和室内试验,得到14个采样点8个监测指标(硝酸盐、高锰酸盐指数、菌落总数、大肠菌群、铁、锰、氟化物、氯化物)的检测值;并根据最大隶属度原则确定隶属度函数,分别计算出隶属度值;然后利用熵权法确定各评价指标的权重,根据隶属度值和权重,运用模糊变换原理得出综合评价结果;最后,运用MapGis、Sufer绘图软件绘制水质等级分区综合评价图。研究表明,菌落总数、大肠菌群和铁是清原县浅层地下饮用水的主要污染物;评价区近1/3的浅层地下水不适合生活饮用。Comprehensive evaluation of the shallow ground drinking water is carried out according to principle of the fuzzy comprehensive evaluation,technology of MapGis and Sufer.First,the 14 water samples were collected and their experimental analysis were carried out,the detection value of eight indexes（nitrate,coliform group,total bacteria,Fe,permanganate index,Mn,fluoride,chloride） is obtained.Membership functions are determined according to maximum membership degree law to calculate the values of membership degree.Then,the weights of the evaluation index are determined based on entropy method.According to the values of membership degree and the weights,the result of comprehensive evaluation is obtained by using fuzzy transformation theory.At last,comprehensive evaluation division map of the water quality is drawed by using MapGis and Sufer.The study shows that coliform group,total bacteria and Fe are the main pollutions of the shallow ground drinking water in the Qingyuan;about 1/3 shallow ground drinking water is not suitable for the life＇s drinking.
